Hello Frogringer
This is not possible.
The only way to share tickets is by forwarding a screenshot of the ticket’s QR code by What’s app message or other app. Or, you forward them the purchase confirmation e-mail which is sent after each successful purchase and also includes the QR code.
Using e-tickets needs the ID or passport of the person travelling. They must be presented physically (no photos) together with their tickets upon ticket inspection.
Kind regards,
Roland
